Reference
Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2011
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
no guideline required
Principles of method if other than guideline:
The mastersizer 2000 (Malvern) is based on the principles of Low Angle Laser Light Scattering (LALLS) in order to determine the particle size distribution. This method is based on the fact that diffraction angle is inversely proportional to particle size, that means, small particles scatter light at wide angles and large particles scatter light at narrow angles.
GLP compliance:
no
Type of method:
Laser scattering/diffraction
Type of particle tested:
primary particle
Type of distribution:
volumetric distribution

Conclusions:
A particle size (PS) distribution of F-3014 sample # 290110574 was measured in water using Mastersizer 2000 (Malvern Instruments).

10% of the volume distribution is below D 10 = 12.844 µm, 50% of the volume distribution is below D 50 = 47.324 µm and 90% of the volume distribution is below D 90 = 131.394 µm
